The recent move by Prime Minister Mark Carney to expedite the construction of a new oil export pipeline to the West Coast is increasing the pressure on Ottawa to make a decision regarding a long-standing environmental issue in the oilsands of Northern Alberta – the management of tailings ponds.
The Alberta government aims to double crude production as oil output in the region is projected to rise. However, the industry, which has been prohibited from discharging water since the inception of the first oilsands mine approximately six decades ago, now confronts the challenge of dealing with extensive tailings ponds filled with decades of industrial mining wastewater, posing risks to wildlife and human health.
Efforts to deter birds and wildlife from the toxic tailings ponds include the constant use of air cannons and scarecrows. The scale of the issue is immense, with the volume of tailings fluid expanding by 50% over a decade, equivalent to the size of 600,000 Olympic-sized swimming pools or submerging the area of the Island of Montreal under three meters of water.
With tailings ponds reaching capacity, the industry is advocating for government regulations permitting the treatment and release of the wastewater. Conversely, some Indigenous leaders are calling for a slowdown in oilsands production until a sustainable resolution is achieved.
Alberta’s Environment Minister Grant Hunter emphasized the importance of advancing scientific solutions rather than maintaining the status quo. Plans are underway for the Alberta government to define the water quality standards necessary for release by the end of the year. Companies assert their capability to treat tailings water effectively but stress the need for clear regulations to guide them.
The debate over treat-and-release revolves around concerns regarding potential environmental and health impacts, especially among Indigenous communities along the Athabasca River. While some companies advocate for treating and releasing water into the river, others like Tũ Nipi Water Solutions are exploring alternatives to reuse tailings water. Indigenous leaders, including Chief Melody Lepine of the Mikisew Cree First Nation, express skepticism and emphasize the need for thorough safety assurances.
The pressure is mounting on Ottawa to make a decision as industry players invest in developing technologies to treat wastewater and address contaminants. Despite ongoing research and testing, Ottawa remains non-committal about its timeline for regulating tailings ponds, prompting calls for action from various stakeholders.
The urgent need to address the environmental challenges posed by tailings ponds underscores the complex interplay between industry interests, environmental concerns, Indigenous rights, and government regulations. The fate of the oilsands industry hinges on finding sustainable solutions that balance economic growth with environmental protection and community well-being.
